Presumably the same bird that overwintered last year. Located yesterday by Noah at (26.5013253, -80.2113624). The bird vocalized at 6:33, and called 5 or 6 times north of the pin, and pretty far back. I started recording on the second or third call note as a flock of grackle flew over. Noah was able to pull one call from the series that wasn’t totally stepped on by the grackle. The spectrogram matches the one obtained yesterday, as well as the ones recorded last year. It shows an upward sloping tuwee call that increases in volume as pitch rises with a slightly curved upper harmonic.
